THOMAS P. LUBY, OF ROCK ISLAND, ILLINOIS, ASSIGNOR T0 ROCK ISLAND PLOWCOMPANY, 0F ROCK ISLAND, ILLILI'OIS, A. CORPORATION OF ILLINOIS.

l CORNvPLANTER.

To all whom t may concern: .Y

Beit known that I, THOMAS P. LUBY, a citizen of the United States ofAmerica, and resident o f Rock Island, Rock Island county, Illinois,have invented a certain new' and useful Improvement in Corn-Planters, ofwhich the following is aspecication.Y`

My invention relates to improvements in corn planters, and particularlyto a four wheel planter in which the wheels are lo- .the opening betweenthe same in order to properly adjust the machine for varying conditions.These and other objects of my invention will be more readily and clearlyunderstood` by having reference to the accompanying drawings in which Ihave illustrated one embodiment of my invention, in which- Figure 1 is aplan view of a machine embodying the features of my invention. Fig. 2 isan enlarged detail view showing porcal sectional view taken on a linepassing through the V-shaped arbor. Fig. 4 is a detail view. Fig. 5 is adetail section on line 5-5 of Fig. 4.

As illustrated, my machine comprises the Y usual frame consisting ofside rails 6 and 7 to which the tongue 8 is secured, which frame carriesthe seed hoppers 9 and furrow openers'l() and the drivers seat 11, allin the well known manner. Carried by side y rails 6 and 7 are a pair ofV-shaped arbors 15, projecting from opposite sides of the frame, whicharbors each carry a pair of driving wheels 12 and 13. As theconstruction of these two arbors and the manner in which the drivingwheels are mounted on the same, are similar, I will describethe-construction only in connection with the right hand arbor,

which is shown in detail in Figs. 3, 4'and 5. This arbor is providedwith a longitudinal extension which projects through the sleeve 17,which sleeve is provided with an upwardly extending lug 18 whichprojects l specificati-on of Letters Patent.

between the cross members 19, being held in position therein by a pairof bolts or pins 20. By providing a series of holes through these crossmembers 19, it will be seen that the sleeve-and the arbor carriedthereby can bereadily adjusted laterally. In order to '..more rigidlysupport the sleeve 17, its upper surface 1s provided with a plurality ofstirrups 18a, one of which is adapted to receive the side railV 7 ineach adjusted position. Loosely mounted on the horizontal portion ofsaid arbor are a pair of sprockets 14 and 16, keyed together so that theoperation of This arbor is also .provided with a V-shaped portion, asclearly shown inv Figs. 2.and 3, on which the two driving wheels 12and13, provided with hubs 21 and 22, are loosely mounted, which hubs areseparated by means of the split sleeve v23. The two driving wheels areconnected together by a universal joint, and likewise sprockets 14 and16 areconnected to the sleeve^21 by a similar universal connection..These universal connections are constructed in the following manner Amember 24 isbo-lted .to the. sprocket 14 and carries Va pair oflaterallyextending arms A25 .whichare pivotally connected Vat* diacarried by thehub 21. This hub is likewise provided with a similar pair of arms 28which are pivotally connected at diametrically opposite points to a ring29. Likewise pivotally connected to this ring are a pair of arms 30carried Vby the hub 22, which arms are connected at points on a lineextending at right angles to the line extending through the points ofconnections to the arms 28.

The sleeve 17 is provided with al pair of 1 slots 31, the marginal edgesof which are provided with corrugations 32. Passing' through these slotsand through the arbor 15 are bolts 33 provided with corrugated washers34 adapted to engage with the corrugations 32, being held in position bythe nuts 35. By this construction it will be readily seen that byloosening the nuts 35 the arbor 15 can be angularly` rotated and thenheld in any adjusted position by again tightening the nuts 35. By meansof this angular adjustment of the arbor, the angularity or tilting ofthe wheels can be varied, and in this manner the point of application ofthe opening between the wheels varied as well as the extent of theseopenings in order to adjust the wheels for varying conditions, theuniversal connections permitting the wheels to operate freely in any ofthe adjusted positions.

As previously stated, the construction of the arbor and the mounting ofthe wheels thereon on the other side of the machine is the same as thatjust described. The winding reel Ll() is conveniently located underneaththe drivers seat 11, being driven by suitable chain and sprocketconnections from the sprocket.

In operation, all the wheels are employed as driving wheels, and theycan be readily adjusted laterally by merely adjusting the position ofthe lug 18 carried by the sleeve 17 with respect to the transverse bars19. Likewise, when it is desired to vary the tilt of the wheels, it ismerely necessary to loosen the nuts and angularly adjust the arbor 15,and then again lock the arbor in this adjusted position.

It will thus be seen that I have devised a very ellicient structure inwhich all four of the wheels can be readily adjusted to suit varyingrequirements. It will likewise be noted that the driving reel isconveniently mounted underneath the drivers seat and is driven from thedriving wheels.

While I have illustrated and described one specific embodiment of myinvention, it will, oit' course, be understood that I do not wish Copiesof this patent may be obtained for to limit myself to the eXactconstruction shown and described but various modifications and changeswill readily suggest themselves to those skilled in the art withoutdeparting in any way from the spirit of my invention.

What I claim as my invention is:

1. The combination of a frame, bearing members laterally adjustablethereon, an arbor mounted in each of said bearings and rotatable thereinto vary the angular positions of the arbor, means for fastening saidarbors in said bearings in their adjusted positions, a pair of wheelsmounted on each of said arbors, a sprocket carried on each arbor, auniversal joint between said sprockets and one of the wheels of eachpair, and another universal joint between the wheels of each pair.

2. The combination or' a planter 'frame having crossed members spacedapart, arbor supporting members positioned between said cross membersand adjustable therein, V- shaped arbors carried by said supportingmembers and rotatably adjustable therein, a. pair of wheels on each ofsaid arbors, a sprocket wheel on each of said arbors between the innerwheel of each pair and the frame, a universal connection between thesprocket and the inner wheel of each pair, and anotheruniversalconnection between the wheels of each pair.

Signed by me at Rock Island, Illinois, this 29th day of May, 1914.
